We brought in producer Glen Ballard, who made Alanis Morissette's Jagged Little Pill, a total pro who really tried to make things happen. We had [new songs] ready within one week. It took three months for Ed to do the guitar parts to three songs and a couple of solos. The Eddie Van Halen I first met could have done that in an hour. When they finally laid down the rhythm-guitar tracks, that was all I needed to sing. I didn't need his guitar solos. As soon as they got that, I went in and knocked out my vocals on all three songs in two hours. Mike came in and we did all the backgrounds in another two hours. Eddie was still asleep. By the time he came down, we were finished. They spent the next three months doing Eddie's guitars.
